The Los Angeles County Board of Supervisors, at the recommendation of Supervisor Don Knabe, extended the expiration of a reward for information leading to the arrest or conviction of whoever raped and robbed a legally blind, 82-year-old woman in Norwalk early in the morning of May 1.

Despite physical evidence, including DNA and a composite sketch of the suspect, sheriff’s deputies have not been able to track down the rapist.

The reward, which would have expired Aug. 17, will now be available until at least Nov. 15.
